Application flled April 17, 1908. Serial No. 427,725-

T 0 all whom it may concern:

Be it known that I, M AR) KNAPP, a citizen of the United States ofAmerica,- residing at 'Dayton,-in the county of (-at taraugus and Stateof New York, have invented new and useful Improvements in Thread andSewingbilk Regulators for Sewing -l\iaehines, of which the following is'a specification.

This invention relates to thread and sewing silk regulators for sewingmachines, and one of the principal objects of thesame is to provide asimple and ellici-ent device to be placed upon the spool post of thesewing machine to prevent the thread from winding around the post.

In using silk thread or wax thread on sewing machines, when the s )001is placed upon the s iool post, it is veryiiable to slip oil the s ooand to wind around the post as soon as i, to feed begins to draw uponthe thread. My invention is intended to overcome this mmoyance, P

In the acoompanyin drawing-Figure 1 is a perspeetive vimv illustratingmy thread and sewing silk regulator applied to the spool post of asewing machine, only a portion of Fig. 2 is a side view of myattachment. Fig. 3 is an edge view of the same. Fig. 4 is an undersideplan view.

Referring to the drawing for a more speeific description of myinvention, the numeral 1 designates the spool post, usually lorated onthe arm 2 ofa sewing machine.

My invention consists of an upright arm 3 provided with a plurality ofthread guiding eyes 4 in the flattened upper )ortionof the same andinclined slots 5 lea ing from the outer edge of said arm into the eyes4. The

eyes 4 are very smooth so thatthe thread will run freely through thesame. A horizontal member 6 is provided with a suitable supportingdevice for the attachment. As shown, a disk 7 is provided with a sleeve8 havin a hole Qtherein of a size to slip readily over the spool post 1.A set screw 10 passes through the sleeve 8 to bear against the spoolpost 1 and hold the attachment firmly in place. There beingltwo eyes 4in the arm 3 spools of different eight may be used an t e threadprevented from running off the spools andwinding on the post by usingthe upper eye for a lon spooland the lower eye for a short one. Si kthread and wax thread are ver' liable to slip oil" the spool immediatelya ter the spool 1s placed upon the post,

- and'niy attaclunent is particularly designed for use with wax threador silk.

My thread and sewing silk regulator may be manufactured at slight cost,can be quickl Y applied for use and has been foundver esirahle andellieient for its purpose.

1 aving thus'describod the invention, what is cl-iirned as new, is:- I

A thread and sewing silk regulator for seaing'znachines comprisingadlSk, an arm extending outwardly therefrom, a vertical arm connectedthereto and provided with a flattened u per end, thread eyes formed'inthe flattene portion and rovided with inclined slots leading into. saieyes, a sleeve under said disk, and a set screw extending throu h saidsleeve to' bear upon the spool post 0 a sewing machine. 1

In testimony whereof I a-ffix my signature in presence of two witnesses.

MARY KNAPP.
